Question

亲爱的所有兄弟姐妹们。最近我创建了一个项目网站。 Everthing工作正常，但问题是当我单击注销时出现以下错误页面。我也在堆栈溢出中寻找同样的问题，然后我尝试了，但我的问题还没有解决。

Object not found!

Apache/2.4.7 (Win32) OpenSSL/1.0.1e PHP/5.5.6 

             **My PHP scripts for check LOGIN.PHP is:**

<?php  


    session_start();    


    $host="localhost"; // Host name

    $username="root"; // Mysql username

    $password=""; // Mysql password

    $db_name="fb"; // Database name

    $tbl_name="users"; // Table name    


    // Connect to server and select databse.

    mysql_connect("$host", "$username", "$password")or die("cannot connect");

    mysql_select_db("$db_name")or die("cannot select DB");    


    // username and password sent from form

    $name=$_POST['email'];

    $password=$_POST['pwd'];

//select data from database    


    $sql="SELECT * FROM $tbl_name WHERE usermail='$name' && userpasswd='$password'";

    $result=mysql_query($sql);    


    // Mysql_num_row is counting table row

    $count=mysql_num_rows($result);    


    // If result matched $myusername and $mypassword, table row must be 1 row    


    if($count==1){

        // Register $myusername, $mypassword and redirect to file "search.php"

        //session_register("$name");

        //session_register("$password");

        $_SESSION['usermail']= $name;

        $_SESSION['userpasswd']=$password;

        header("location:home.php");    
    }

    else {

        $msg = "Wrong Username or Password. Please retry";

        header("location:ErrorPage.html");      

    }

?>
                  **PHP script for HOME.HTML**
<?php

session_start();

require("checklogged.php");

?>
                  **My LOGOUT.PHP script is:**

<?php
session_start();
$_SESSION['usermail'] ='$name';
$_SESSION['userpasswd']='$password';
session_unset();
session_destroy();
header("Location: login.html");//This is my initial login page
?>

Answer 1

您收到404错误，这意味着您没有将home.html文件放在logout.php文件中。尝试将其更改为index.php或login.php（如果有）

喜欢这个......

session_unset();
session_destroy();
header("Location: index.php"); //<-- Change here
?>

Answer 2

使用header()，您最好使用完整的网址。或者，至少添加正斜杠：header("Location: /home.html");

Answer 3

可能是对页面的引用不正确，即注销页面与主页不同的目录使用../如果需要则提供目录级别或使用完整的URL，如：

 header("Location: http://www.mysite.com/home.php");

PHP：退出问题？
